Kinetics of the hydrogenation of fatty oils

Hydrogenation results for fatty oils were analyzed by using a nonlinear least squares method. The rate of the hydrogenation for diunsaturated fatty groups to monounsaturated groups and the rate of the geometrical isomerizations between monounsaturated groups were found to be half order with respect to hydrogen concentration, whereas the hydrogenation rate of monounsaturated groups was the first order. A detailed reaction mechanism is presented to explain the kinetic behavior.
